COMPANY, OF NEWARK, NEW JERSEY, A CORPORATION OF NEWV JERSEY ras'rnnr aroe RIST WATCH sTRAPs Application filed. April as,

This invention relates to improvements in fasteners for wrist watchbands, with special reference to types in which the main portions of theband are made of soft, flexible material, such as finished leather orsimilar material.

Ordinary leather bands, used for this purpose, are objectionable, forthe reason that they require threading the end of one section of thestrap into the buckle loop. Unless this is done very carefully, thewatch may be accidentally dropped. Furthermore, after the end of thestrap has been threaded through the loop, it must be engaged with thetongue of the buckle, and the projecting end of the strap must beinserted through the usual leather loop on the buckle section of thestrap which may result in an unsightly appearance, and a curling of theend of the strap.

It is therefore an object of the present invention to provide a fastenerfor a wrist watch strap easy and safe to adjust on any size wrist and tohold the watch safely, securely and comfortably thereon. Even if thestrap ends are not buckled or locked together, there is safety againstloss or breakage, and a neat appearance throughout the. life of thestrap is obtained.

The elements set forth comprise a construction which is simple,economical to manufacture and ornamental in its nature. It is also veryeasy to operate on the wrist of the wearer and comfortable when worn,there being no projecting parts to press against or bruise the skin.

These advantageous objects are accomplished by the novel and practicalconstruction and arrangement of parts hereinafter fully described andshown in the accompanying drawing, constituting a component of thisdisclosure, and in which Figure 1 is an edge view of a wrist watch bandmade in conformity with the invention.

Figure 2 is a plan view of the same.

Figure 3 is a fragmentary sectional View taken on line 3-3 of Fig. 2 anddrawn to an enlarged scale.

This device consists mainly of two straps, 5 and 6, of suitablethickness, preferably of 1921. Serial no. 533,403.

soft, high grade leather, ornamented if desired on their-outer surfacesand smooth on their inner surfaces which contact the wrist.

At the opposed outer ends of each strap are hollow bars 7 and 8 whichprovide the usual means for connecting with the frame of a watch casing,as clearly shown, these bars being formed with rearwardly extendingclamp members between which the strap ends are firmly secured. Sewedloops on the said outer ends could alsobe employed, if desired.

The strapb contains acentral row of perforations 9' spaced apart, andhas fixed on its opposite end a clasp 10 in which is pivoted a loop 11closely encircling the adjacent strap 6, acting as a loose keeper forit.

On the end of the strap 6 is secured a clasp 12 in which is pivoted aleaf l3 provided-with a bent hoolgl l adapted to be selectively en-'gaged many of the perforations 9 of the strap 5 thereby to lengthen andshorten the operative length of the band at will.

The hook 14 is constructed with a hinge at 13 to permit of the easyremoval of the hook from engagement with the other'strap,the relativelength of the hook-the bend-and the point of turning, all beingimportant factors in obtaining a proper operative arrangement.

As stated above, my invention provides a measure of safety against loss'or breakage of the wrist watch even though the strap ends are notsecured together by insertion of the hook 14 in one of the perforations9. Because of'the proportioning of the loop- 11 and the hook 14:, it isimpossible forthe Strap ends to be separatedby pulling the loop 11overthe'hook 14. Hence the straps 5 and 6 are at all times securedtogether, and the wrist watch cannot be removed from the wrist except bypassage of the complete band over. the, hand.

,Although the foregoing is descriptive of the preferred embodiment ofthe invention, it will be apparent that minor changes may be made in itsconstruction, without the exercise of invention or conflicting with thescope of the claims hereto appended.

Having thus described the invention, what ice is claimed as new anddesired to secure by Letters Patent, is

1. A fastener comprising a pair of overlapping strap ends, a looppivotally secured to the end of one strap for receiving the overstrap,said loop-carrying strap having a cen tral roW of spaced perforations,and a hinged hook member on the inner end of the said overstrap adaptedto be selectively engaged in any of the said perforations.

2. A fastener comprising a pair of overlapping strap ends, a looppivotally secured to the end of one strap to receive and slidablyengagethe overstrap, said loop-carrying strap having a series oflongitudinally spaced perforations, a clasp on the inner end of theoverstrap, a leaf pivoted in said clasp, and a re-entrantly turned hookon said leaf for selectively engaging said perforations,

the re-entrant portion of the hook extending a suflicient length toprevent accidental disengagement during use.

3. A fastener comprising a pair of overlapping strap ends, a looppivotally secured to the end of one strap to receive and slidably engagethe overstrap, said loop-carrying strap having a series oflongitudinally spaced perforations, and a re-entrantly turned hookpivotally secured to the inner end of the said overstrap adapted to beselectively engaged in any of'the said perforations.

4. A fastener comprising a pair of overlapping strap ends, alooppivotally secured to the end of one strap to receive and slid- 5ably engage the overstrap, said loop-carrying strap having a series oflongitudinally spaced perforations, and a hook pivotally secured to theinner end of the said overstrap adapted to be selectively engaged in anyof 49 the said perforations, said loop and said hook being soproportioned as to prevent said straps from being separated at theirinner ends.

5. A fastener comprising a pair of over- 45. lapping strap ends, a looppivotally secured to the end of one strap to receive and slidably engagethe overstrap, said loop-carrying strap having a series oflongitudinally spaced perforations, and a re-entrantly 50 turned hookpivotally secured to the inner end of the said overstrap adapted to beselectively engaged in any of the said perfora-w tions, said loop andsaid hook being so proportioned as to prevent said straps from beingseparated at their inner ends.
